FU SHENG SR SERIES SCREW REFRIGERANT COMPRESSORS
A MASTERPIECE OF MODERN TECHNOLOGY WHICH OFFERS YOU HIGH EFFICIENCY AND ENERGY - SAVING

 
FU SHENG SR SERIES SCREW REFRIGERANT COMPRESSORS

Introduction : Founded in 1953, Fu Sheng always strives to maintain a consistent managerial philosophy of pursuing excellence and enriching life. Fu Sheng has made every effort to ensure that customers are provided with compressors of the highest quality. After years hard work, Fu sheng has been providing compressors in more than sixty countries all over the world.

keeping growth is the basic condition of survival in the competitive market. For years, Fu Sheng has been keeping on improving manufacturing facility and technology. A plant automation project was initiated in 1987, which incorporated Managerial information Systems (MIS), Engineering information Systems (EIS) and Flexible Manufacturing Systems (FMS). With this integrated Systems, the management level is able to access the valuable information which benefits to the improvement of product design.

Advanced CNC Machining Centers and Rotor Milling Machines are used to manufacture compressors. All of the parts and casings of the compressor are precisely milled under humidity and temperature control room and then a sophisticated coordinate measuring machine is used to inspect the dimension of finished parts. Compressor rotors are dynamically balanced before assembly. Under fu Sheng quality control system, every screw compressor shall be tested before shipment.

  • High EER, Low Energy Consumption
    The newly asymmetrical rotor profile, which has five lobes ad six flutes in the male and female rotors respectively, results in a low pressure differential between flutes and provides high volumetric efficiency but low power consumption.

  • Low Noise Level, Low Vibration
    Rotors are precisely processed and dynamically balanced. supported by high precise bearings, rotros can run smoothly.

  • Precise Capacity Control System
    four - step or linear capacity control system is available for operation under variable loading conditions with minimum power consumption.

  • Ease of Maintenance
    The semi-hermetic design and limited components used, the detachable motor construction makes compressors easy to maintain.

  • Wide Application Range
    The compressors can be widely used in water and air-cooled air-conditioning systems, thermal storage systems, heat pumps or industrial processes if external oil cooler, economizers or liquid refrigerant injection devices is equipped.
Coordinate Measuring Machine

All finished components are inspected to assure the highest quality of products.

Calorimeter

Experimental data always reflect the performance of a compressor.
With this facility, engineers can easily get a lot of information of the compressors which is critical to optimize the design and improve the function of the compressor from time to time.
